WHO names new COVID variant omicron, cautions against travel measures******

The World Health Organization on Friday classified the B.1.1.529 variant detected inSouth Africa as a SARS-CoV-2 "variant of concern," saying it mayspread more quickly than other forms.。

Preliminary evidence suggested there is an increased risk ofreinfection and there had been a "detrimental change in COVID-19epidemiology," it said in a statement after a closed meeting ofindependent experts who reviewed the data.。

Infections in South Africa had risen steeply in recentweeks, coinciding with detection of the variant now designatedas omicron, WHO said.。

"This variant has a large number of mutations, some of whichare concerning. Preliminary evidence suggests an increased riskof reinfection with this variant, as compared to other (variantsof concern), it said.。

Omicron is the fifth variant to carry such a designation.。

"This variant has been detected at faster rates thanprevious surges in infection, suggesting that this variant mayhave a growth advantage," the WHO said.。

Current PCR tests continue to successfully detect thevariant, it said.。

Earlier, the WHO cautioned countries against hastilyimposing travel restrictions linked to the variant of COVID-19,saying they should take a "risk-based and scientific approach." Global authorities reacted with alarm to the new variantdetected in South Africa, with the EU and Britain among thosetightening border controls as scientists sought to find out ifthe mutation was vaccine-resistant.。

"At this point, implementing travel measures is beingcautioned against," WHO spokesman Christian Lindmeier told aUN briefing in Geneva. "The WHO recommends that countriescontinue to apply a risk-based and scientific approach whenimplementing travel measures."

It would take several weeks to determine the variant'stransmissibility and the effectiveness of vaccines andtherapeutics against it, he said, noting that 100 sequences ofthe variant have been reported so far.。

People should continue to wear masks whenever possible,avoid large gatherings, ventilate rooms and maintain handhygiene, Lindmeier added.。

Mike Ryan, WHO's emergency director, praised South Africanpublic health institutions for picking up the signal of the newvariant.。

But he warned that while some countries had systems in placeto do this, the situation elsewhere was often unclear."So it's really important that there are no knee-jerkresponses here. Especially with relation to South Africa," hesaid. "Because we've seen in the past, the minute that there isany mention of any kind of variation, then everyone is closingborders and restricting travel."

Hertha Berlin edge Monchengladbach in Bundesliga******

BERLIN, Oct. 23 (Xinhua) -- Marco Richter's sole goal was enough for Hertha Berlin to secure its second straight win after beating Borussia Monchengladbach 1-0 in the 9th round of Bundesliga on Saturday.

The "Foals" left no doubt that they were in search of a win in the German capital as Nico Elvedi came close with a header in the fifth minute.

Monchengladbach then got a foul play penalty awarded but it was a short-lived joy as the referee overturned his decision after reviewing the situation in the 10th minute.

Hertha defended deep and showed no intentions to push forward while Breel Embolo should have marked the opener for the visitors, but the striker missed the target from inside the penalty area eight minutes later.

Monchengladbach was the more active team as Elvedi unleashed another dangerous header following a corner from Jonas Hofmann, but the goal was scored at the other end of the pitch as Richter made use of a deflected ball and clinically scored against the run of the game with a sideways scissor-kick in the 40th minute.

The hosts almost flabbergasted Monchengladbach with the 2-0 lead but Yann Sommer was equal to Marton Dardai's close-range header just before the break.

After the restart, Monchengladbach took the reins again, but Hertha's defence stood firm and kept the "Foals" at bay.

Hertha goalkeeper Alexander Schwolow had nothing to do as Monchengladbach's only clear-cut chance came in the 84th minute when substitute Patrick Herrmann rattled the side netting from tight angle.

With the result, Hertha Berlin jump on the 10th position while Borussia Monchengladbach slip to the 12th spot in the table.

"It is a really upsetting defeat. Hertha won this game after making use of just one chance. We dominated the proceedings and gave things away. I am not happy that we weren't able to grab a point here," said Monchengladbach head coach Adi Hutter.

"I think it is a deserved win for us. We should have added another goal to our lead in the second half, but overall, we defended very well and were patient," said Hertha head coach Pal Dardai.

The following encounters conclude the 9th round on Sunday: Cologne clash with Bayer Leverkusen, Stuttgart face Union Berlin, and newly promoted Bochum meet Eintracht Frankfurt. Enditem
